Abstract

There is provided a container closure that can easily be manufactured, has improved drop strength and is convenient for opening operation. The present invention provides a container closure which comprises, a substrate (1) having adequate property for retaining an object which is enclosed in a container, a peripheral section (5b) formed on the periphery area of the container closure on the opposite side of a side where the substrate (1) is attached to a container body, a panel section (6) covering an area of the substrate (1) surrounding by the peripheral section (5b) on the same side where the peripheral section (5b) is provided, and a score section (7a) formed between the peripheral portion (5b) and the panel section (6) to provide a weakened region (7b), the peripheral section (5b) and the panel section (6) is a plastic layer formed with the same heat-fusible plastic on the substrate (1). Substantial area of the score section (7a) is constructed of the substrate (1). Further, the thin layer is formed on at least a part of the substrate (1) of the score section (7a) with the heat-fusible plastic that connects the peripheral section (5b) and the panel section (6).
